Explore the different groups of the periodic table. Explore now Periodic table with ionic charges Explore the periodic table labeled with common ionic charges of the elements. Explore now Periodic table with valence electrons Explore the periodic table labeled with valence electrons of the elements....
The alkali metal family includes the six elements in thefirst columnof the periodic table, fromlithium(Li) down to francium (Fr). These metals all contain one valence electron, meaning they form cations and react readily with water. These elements form the ionic bonds known as salts. Hydrogen...
What is a periodic table and how many groups of elements does it consist of? Based on the periodic table, what do we now call the element Mendeleev? Which group in the periodic table contains elements with the valence electron configuration of ns^2np^1? Please explain!!
Mendeleev’s introduction of the periodic table of elements is one of the most important milestones in the history of chemistry, as it brought order into the known chemical and physical behaviour of the elements. The periodic table can be seen as paralle

Also called groups, what is the name for vertical columns of elements on the periodic table? What is the name of the Group of the Periodic Table in which all the elements have a valence shell electron configuration ns^2np^0? Name the first and second elements of the periodic table...
Groups in the Periodic Table of Elements Click on an element to read about the chemical and physical properties of thegroupto which that element belongs. Alkali Metals Less dense than other metals One loosely bound valence electron Highly reactive, with reactivity increasing moving down the group ...
In which region of the periodic table would an element with the electron configuration below be located? 1s^22s^22p^63s^23p^64s^13d^4 a) Halogens, group 17 b) Transition metals, groups 3-12 c) Alkali metals, group 1 d) Noble gases, grou...
The columns that comprise the periodic table are calledgroups-- 18 in total. Groups indicate elements with similar chemical and physical properties. About 80 percent of the elements aremetals(shiny elements that conduct heat andelectricitywell), and 15 percent of the elements arenonmetals(poor...
Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through ...
